Diagnostics are based on the use of unconditioned predictions (i.e., predictions that are not adjusted for monitoring loads). These predictions (and the associated residuals and observed to predicted ratios shown in the following section) provide the best measure of the predictive skill of the estimated model in simulation mode. The simulated predictions are computed using mean coefficients from the NLLS model estimated with monitoring-adjusted (conditioned) predictions.
